Noise Cut Transformer NCT-K

Noise Cut Transformer NCT-K

It is equipped with strict lightning protection and surge prevention.

The lightning surge that intrudes into the power line and reaches one coil of the lightning protection transformer first attempts to transfer electrostatically (through capacitive coupling) to the other coil. However, if the transformer has a shielding plate, this can be effectively prevented. Following this, a slower electromagnetic transfer (through inductive coupling) occurs, and there has been no lightning protection transformer equipped with a structure to prevent this; they have relied on added capacitors and varistors, which have been insufficient to protect low-resistance information devices and precision electronics. However, a structure like the "Noise Cut Transformer," which prevents high-frequency magnetic flux from lightning surges from crossing to the secondary side, can also prevent this electromagnetic transfer. The NCT-K type takes advantage of this characteristic, featuring high voltage insulation that withstands lightning surge impacts, excellent shielding with a very low impedance triple structure, and is designed and manufactured to easily direct powerful lightning surges to the ground, almost completely preventing them from escaping to the load side, making it a "Noise Cut Transformer for lightning protection."

[Countermeasure Example] When the painting robot operates, the leakage breaker trips.

[Countermeasure Example] When the painting robot operates, the leakage breaker trips.

Leakage current detected! No wiring faults or insulation issues found; where could the cause be?

Company A, which develops and manufactures painting robots, has a customer who has decided to initially adopt one set of the new robot on a trial basis. If all goes well, there is a significant possibility of introducing five sets in the future. The equipment was delivered, and the adjustment work was progressing smoothly. It seemed that we would soon be able to hand it over to the customer. However, suddenly the customer reported, "The existing painting robot's ground fault circuit interrupter is tripping irregularly. It seems that a ground fault occurs when the new robot starts or stops. We cannot proceed with the acceptance inspection under these circumstances!" *For more details, please refer to the PDF document or feel free to contact us.*

Basic Knowledge and Countermeasures for Noise in AC Power Systems

Basic Knowledge and Countermeasures for Noise in AC Power Systems

Introducing troubleshooting on-site using expressions that are as easy to understand as possible!

In recent years, manufacturing equipment, control devices, and inspection devices have been miniaturized, enhanced in performance, and made more labor-saving, leading to faster control signals and lower operating voltages. As a result, they tend to be more susceptible to noise, but due to the increasing complexity of control processes, it has become difficult to identify the causes of noise-related issues, making it challenging to implement noise countermeasures. This document introduces the types and characteristics of noise in AC power systems, as well as countermeasure methods, from the perspective of troubleshooting in the field, using expressions that are as easy to understand as possible. [Contents (excerpt)] ■ Types of power supply noise ■ Transient noise and continuous noise ■ Noise propagation paths and loops *For more details, please refer to the PDF document or feel free to contact us.

[Case Study] Pharmaceutical Manufacturer C Research Institute

Unexplained stoppage of the centrifuge, what is its true nature? Here we present a case that achieved stable operation of research equipment!

At the C Research Institute, research and development of new drugs is underway, and many facilities are operational; however, there were issues occurring. It was speculated that the cause might be the deterioration of the power supply environment due to voltage fluctuations, but this remained merely a hypothesis, and we were troubled. Since there are various factors that can deteriorate the power supply environment, we first proposed the introduction of high-frequency noise countermeasure products that could be implemented at a low cost and provided a trial unit. When we attached a "Noise Cut Transformer" to the centrifuge to see if the situation would change, the issues that had occurred daily ceased entirely from the first day of implementation. Subsequently, we introduced the solution to the devices that had experienced issues, and those devices also stopped having problems, achieving stable operation of the research equipment. 【Case Summary】 ■ Problem: Unable to identify the cause of the issues ■ Proposal: High-frequency noise countermeasure products that can be implemented at a low cost ■ Introduced Product: Noise Cut Transformer ■ Result: Troubles resolved through high-frequency noise countermeasures ■ Conclusion: It is important to implement measures suitable for the factors causing disturbances that deteriorate the power supply environment. *For more details, please refer to the PDF document or feel free to contact us.
